    • Characterization of metal oxide-based gas nanosensors and microsensors fabricated via local anodic oxidation using atomic force microscopy 

      Archanjo, Braulio Soares; Fernández Siles, Pablo Roberto; Oliveira, Camilla K. B. Q. M.; Baptista, Daniel Lorscheitter; Neves, Bernardo Ruegger Almeida (2013) [Artigo de periódico]
      Thiswork reports on nanoscale and microscalemetal oxide gas sensors, consisting ofmetal-semiconductor-metal barriers designed via scanning probe microscopy. Two distinctmetal oxides, molybdenum and titaniumoxides, were ...

    • Fabricação de dispositivos com contato túnel para spintrônica em grafeno 

      Canto, B. (2014) [Tese]
      Neste trabalho é apresentado em detalhe a fabricação de dispositivos com contato túnel em grafeno, com foco nas caracterizações físico-químicas de barreiras túnel de Al2O3, crescidas sobre grafeno. Uma investigação detalhada ...

    • Influence of impurities on the luminescence of Er3+ doped BaTiO3 nanophosphors 

      Webler, Geovana Dresch; Zapata, Maximiliano Jesús Moreno; Maciel, Glauco Santos; Patra, Amitava; Hickmann, Jandir Miguel; Alencar, Marcio André Rodrigues Cavalcanti de (2014) [Artigo de periódico]
      The influence of the presence of barium carbonate (BaCO3) phase on the luminescence properties of barium titanate nanocrystals (BaTiO3) powders was investigated. Structural and optical characterizations of erbium (Er3+) ...

    • Magnetization dynamics in nanostructures with weak/strong anisotropy 

      Andrade, Antonio Marcos Helgueira de; Corrêa, Marcio Assolin; Viegas, Alexandre da Cas; Bohn, Felipe; Sommer, Rubem Luis (2014) [Artigo de periódico]
      We investigate the high-frequency response of magnetization dynamics through magnetoimpedance (MI) effect in Permalloy-based multilayered thin films produced with two different non-magnetic metallic spacers: Cu and Ag. Due ...

    • Third-order nonlinear optical response of colloidal gold nanoparticles prepared by sputtering deposition 

      Castro, Hermerson Pablo Silva; Santos, Heberton Wender Luiz dos; Alencar, Marcio André Rodrigues Cavalcanti de; Teixeira, Sergio Ribeiro; Dupont, Jairton; Hickmann, Jandir Miguel (2013) [Artigo de periódico]
      The nonlinear optical responses of gold nanoparticles dispersed in castor oil produced by sputtering deposition were investigated, using the thermally managed Z-scan technique. Particles with spherical shape and 2.6 nm of ...
